Abstract: 1,104,602. Gear pumps. M. TUROLLA. March 30, 1966 [April 3, 1965], No. 14144/66. Heading F1F. A gear pump comprises two externally-meshing gears 6, 7, Fig. 1, having spindles 106, 107 supported by axially-movable bearing-plates 8 that are pressed against the gears by fluid entering chambers 17 adjacent the axially-outermost faces of the plates from the high-pressure side of the pump through passages 18 within the plates, flexible sealing-rings 19 being lodged between said faces of the plates and end covers 4, 5 for the casing 1, which rings overlap junctions between the casing and the plates, Fig. 2, to prevent leakage of fluid from the chambers 17 into a suction duct 2 and to facilitate manufacture of the pump. Preferably, the rings 19 also overlap the associated junctions on the high-pressure side of the pump, as shown in Fig, 2. The rings 19 may overlap the whole of each of the associated junctions. Bosses 12 on each of the plates 8 engage with bores 13 in the adjacent end cover to define therewith chambers 14 that communicate with the lowpressure side of the pump through passages 15.

Abstract: 694,221. Lathe details. SCHUETTE, A. H., COMMER, G., WELCKER, L., and PECHMANN, E. F. VON, [trading as SCHUETTE, A. H. [Firm of]]. June 14, 1951 (Oct. 13, 1950], No. 14158/51. Class 83 (iii). In an automatic lathe or like machine-tool in which the feed movement of the tools is carried out by continuously rotating cams, rapid forward and backward movement of the tool required in drilling deep holes is effected by hydraulic means operating a piston member coupled to the tool, the hydraulic means being in turn controlled by a cam. A drill 16 is carried in a holder 15 secured to a hydraulic piston 14 slidable in a cylinder 13. The latter slides along ways on the bed and carries an extension with a follower roller 36 to engage campieces 12, 12<SP>1</SP>, 27 on a drum 11. The cams 12, 121 control the stepped feed movement of the drill and during the dwell between feed movements the back of cam 121 is utilized at 25 to operate a spring-pressed reversing valve which withdraws the piston 14 and drill to clear swarf prior to the next feed movement. Movement by cam surface 25 back to its initial position allows valve 18 to reverse the fluidpressure to the cylinder and the drill is moved back to a position ready for feed-movement by the cam 121. Cam 27 finally withdraws the drill. The cylinder may be stationary and the tool pressure during feed may be hydraulic with the cams controlling the feed movement.
